Copy and Paste: Gene Cloning Explained

If an organism reproduces without a partner and passes on 100% of its genetic material to its offspring, Then that offspring is genetically identical. If the offspring is genetically identical, Then it is defined as a natural clone.

If genetic diversity requires the shuffling and recombination of DNA from two parents, and If asexual reproduction only copies the DNA of one parent, Then the offspring remain identical. If they are identical, Then the genetic diversity does not increase.

If the goal is to produce two daughter cells with the exact same number and type of chromosomes as the parent, Then the cell must undergo mitosis. If mitosis creates identical copies, Then it is the basis for cloning.

If an embryo develops to maturity without the need for male sperm, Then the resulting offspring is a clone of the mother. If this occurs naturally in vertebrates, Then the term for the process is parthenogenesis.

If an organism splits in two (fission), grows an outgrowth (budding), regrows from a piece (fragmentation), or uses unfertilized eggs, Then it is cloning itself. If cross-pollination requires two plants, Then it is sexual, not asexual.

If all individuals in a population are clones, Then they all share the same genetic weaknesses. If a new disease or environmental shift occurs that kills one individual, Then it is likely to kill the entire population.

If a plant grows a horizontal stem or storage organ to create a new individual, Then it is cloning its own tissue. If seeds result from pollen and egg interaction, Then they are sexual; however, grafting uses existing tissue to clone.

If a yeast cell or a hydra develops a small replica of itself on its body wall, and If that replica becomes independent, Then the process is identified as budding.

If a female provides all the chromosomes for the offspring and no male DNA is involved, Then the offspring is a genetic copy of the parent. If it is a copy from one parent, Then it is a form of cloning.

If parasites evolve quickly to "unlock" host defenses, and If clones have identical "locks," Then the parasite will eventually kill all clones. If sex shuffles the genes, Then it creates new "locks" that parasites must re-learn.

If a single-celled prokaryote replicates its circular DNA and pinches into two equal halves, Then it has cloned itself. If this is the standard method for bacteria, Then it is binary fission.

If an organism has high regenerative capabilities, Then a lost limb or body segment can grow the missing parts. If that segment becomes a whole new organism identical to the original, Then fragmentation has achieved cloning.

If a female shark in an aquarium is isolated from males and produces a pup, Then she has switched methods. If she uses her own DNA to create offspring only when necessary, Then she is a facultative cloner.

If a sexual population has males and females, Then only the females produce offspring. If an asexual population is all female, Then every individual can reproduce. If every individual reproduces, Then the population grows twice as fast.

If a lineage cannot remove harmful mutations via sex, Then they accumulate (Muller's Ratchet). If clones are used, Then the population stays the same (stasis) and can fill an area quickly, but lacks the ability to adapt to new threats.

If there is no mixing of genes from two parents, Then the DNA sequence stays the same unless an error occurs during copying. If an error occurs in the body cells, Then it is a somatic mutation.

If a plant produces a seed that contains an embryo genetically identical to the mother, Then it has skipped the sexual process. If this occurs without the fusion of gametes, Then it is called apomixis.

If HGT involves the movement of DNA between existing bacteria, Then it is a way to get variation. If cloning is the creation of a new identical individual, Then they are different processes even though both occur in bacteria.

If an organism is perfectly adapted to its current home, Then any change in its DNA might make it less fit. If cloning keeps the DNA exactly as it is, Then the successful traits are preserved perfectly for the next generation.

If cloning is fast and produces identical copies across bacteria, archaea, and eukarya, Then it is a universal strategy. However, If the environment changes, Then sexual reproduction is often superior, so Answer E is false.
